plogr vs rwasm
A side-by-side editorial comparison of plogr and rwasm — release velocity, themes, recent moves, and the top alternatives to consider.

plogr vs rwasm: at a glance
What is plogr?
A logging header for Rcpp packages that sat untouched for nine years, then changed how it switches on
plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.
What is rwasm?
The toolchain that gets R packages into the browser is optimising for payload size, not features.
rwasm cross-compiles R packages to WebAssembly and assembles the virtual filesystem images that webR loads. Its three releases have moved from making cross-compilation work at all — Autoconf overrides, uname and pkg-config shims, OpenMP support — to controlling how the resulting artefacts are packaged and shipped. Every release is pinned to a specific webR version floor.

◆ Current state
plogr ships a stripped build of the plog C++ logging library as an R package, so other packages with C++ code can log through REprintf() and have output land in the R console rather than stdout. It is a header-only dependency with no R-level API to speak of. Three releases in September 2016 established it; the next arrived in November 2025.
◆ Where it's heading
There is almost no trajectory to read here, which is itself the finding — the package was finished in a week and stayed finished. The 2025 release is the first change in nine years and it tightens the activation contract: logging now does nothing unless PLOGR_ENABLE is defined at compile time, so packages depending on it get silence by default rather than unexpected output. A GCC-specific fix for function names in multi-argument template classes lands alongside.
◆ Prediction
With the activation macro now explicit, dependent packages that assumed logging was on will need to define it; beyond that the entries give no basis for expecting further development.
rwasm
0.0INFRA · APIS
The toolchain that gets R packages into the browser is optimising for payload size, not features.
◆ Current state
rwasm cross-compiles R packages to WebAssembly and assembles the virtual filesystem images that webR loads. Its three releases have moved from making cross-compilation work at all — Autoconf overrides, uname and pkg-config shims, OpenMP support — to controlling how the resulting artefacts are packaged and shipped. Every release is pinned to a specific webR version floor.
◆ Where it's heading
The arc runs from correctness to delivery. The first release fought the cross-compilation environment itself, isolating builds from host libraries and shimming the tools configure scripts expect. The second replaced Emscripten's own file_packager with a custom metadata path and added gzip compression for filesystem images. The third is pure coordination, rebuilding the build system for webR 0.5.0. That cadence — roughly annual, each release gated on a webR version — makes this a component of the webR release train rather than an independently moving project.
◆ Prediction
The next release will most likely follow the next webR version, since two of three releases so far have been driven by a webR floor rather than by rwasm's own agenda.
